Madhya Pradesh: Another Congress MLA quits, number rises to 20

New Delhi, Jan 12: A fact-finding committee of the Congress on the JNU violence on Sunday said the January 5 attack inside the university campus was "state-sponsored" and recommended Vice Chancellor M Jagadesh Kumar be dismissed and criminal investigation initiated against him.

The Congress had appointed a four-member fact-finding committee to carry out a detailed inquiry into the violence at the Jawaharlal Nehru University (JNU).

Sushmita Dev, member of the committee, said the committee recommended that Kumar should be dismissed immediately and all the appointments in faculty should be probed and independent inquiry should take place.

"Criminal investigation must take place against the VC and faculty members and the security company," the Mahila Congress chief said.

"It is clear that the attack on JNU campus was state-sponsored," Dev said.

She also demanded a complete rollback of the JNU fee hike.

The other members of the fact-finding committee are Hibi Eden, MP and former NSUI president, Syed Naseer Hussain, MP and former president of JNU NSUI and Amrita Dhawan, a former NSUI president and ex-DUSU president.

On January 5 night, masked people armed with rods and sticks stormed the JNU campus and assaulted students and faculty members, and vandalised property, leaving several people injured.

Leftist outfits and the RSS-affiliated Akhil Bharatiya Vidyarthi Parishad (ABVP) blamed each other for the violence.

May 27: At a time when India is struggling with the deadly coronavirus, huge swarms of locusts in many states has bought nightmares to the farmers.

Experts warn of extensive crop losses if authorities fail to curb the fast-spreading swarms by June when monsoon rains spur rice, cane, corn, cotton, and soybean sowing.

Locusts entered India after traveling from Africa through Yemen, Iran and Pakistan.

After massive devastation in Pakistan, t swarms of locusts entered India through Rajasthan and Gujarat. The number is so large that the farmers and authorities are feeling helpless in tackling the threat.

The situation has become more alarming as the locusts is spreading across the country at an extremely fast rate. After badly affecting the crops in Rajasthan, Gujarat, Maharashtra, and Madhya Pradesh, the swarm of locust have now entered Uttar Pradesh.

In Rajasthan alone, the locust attack has damaged 5 lakh hectares of crop and nearly 17 districts of Madhya Pradesh have also seen their terror. Earlier from May 2019 to February 2020, too, the locust swarms entered India several times.

Speaking on the current situation, Dr Ram Pravesh, District Agricultural Officer, Agra, Uttar Pradesh said the Department of Agriculture is working with farmers in dealing with the situation. He urged the farmers to inform their Mandal Krishi Adhikari if they require any help.

India's largest-ever locust attack was in 1993 when more than three lakh hectares of cultivated land were completely destroyed.

Earlier in 2020, farmers salvaged their wheat and oilseed crops from a previous locust scourge.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.
